我正在做一个项目，我必须在 gridview 中返回以下列，并且可以通过 0-7 过滤器缩小搜索范围。
- 应用ID
- 客户姓名
- 项目编号
- 项目编号
- 项目名称
- 应用类型
- 应用子类型
- 节点名
- 用户名
我可以在我的本地机器上很好地完成这项工作，但是当我在服务器上运行它时，它会返回一个错误，指出它无法在数据库源中找到 ProjectTitle 字段。其余代码没有问题，因为当我从 GridView 中删除 ProjectTitle 列时没有显示任何错误。以下是我的代码。

对于导致此问题的原因有什么建议吗？
最佳答案
您确定远程数据库包含字段 ProjectTitle 吗？
如果您更改本地主机连接字符串 localhost 以便它使用远程数据库(但仍在使用本地主机项目)，您是否仍然会收到错误消息？ (这将判断问题是出在代码上，还是出在数据库上。)
关于c# - GridView : Database error when running on server, 在本地主机上工作正常，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/12496313/
